Extract Vector Data by Field Group
Overview
Extract vector data from the Input vector file by field group and output the organized results.
This tool is mainly used to organize data based on feature attribute tables or geometry columns. Before processing, confirm the field structure, encoding, and output format support for attribute fields in the input layer.
Use Cases
- Quickly generate standardized results when vector data needs to be extracted by field group.
- Use as an intermediate step in a longer GIS processing chain before subsequent analysis.
- Improve efficiency in batch processing, repeated execution, or standardized delivery workflows.
Parameters
| Parameter | Description | Notes |
|---|---|---|
| Input vector file | The vector file to extract by group. | Required |
| Group field | The field used for grouping. Multiple vector files are extracted according to the distinct values in this field. | Required |
| Output vector folder | The folder where grouped extraction results are saved. One file is generated for each group. | Required |
Steps
- Start the tool: Open the Geoprocessing Toolbox > go to Vector Tools > Feature Processing > Select > start the Extract Vector Data by Field Group tool pane.
- Prepare the input: Select the Input vector file by data type, and confirm that the input data is complete and can be read correctly.
- Set core parameters: Configure the grouping field according to your workflow goal. If needed, check the field type and field values before running the tool.
- Set the output: Specify the output parameters, and confirm that the output path, format, and naming rules meet downstream requirements.
- Run and check the result: Click Run to execute the task. After completion, check whether the result extent, value distribution, field structure, and spatial location meet expectations.
Notes
- Before running batch processing on production data, validate the parameter settings with a small sample dataset.
